Disease Ecology



The main objective of disease ecology is to understand the influence of environmental factors and to predict when and where a disease is most likely to occur

decision making, planning of prevention, management and/or response actions, etc.

Landscape Epidemiology


5 components:

  1. animal donors;
  2. vectors;
  3. animal recipients;
  4. the pathogenic agent,
  5. the influence of factors of the external environments


Spatial interactions between these agents in a landscape explain patterns of infection risk and may contribute to disease emergence.

Applications of geospatial technologies

  • Spatialisation of outbreaks (space-time patterns and causes)
  • Hosts and vector distribution mapping
  • Estimation of environmental indices and monitoring of favorable environmental conditions
  • Disease risk mapping and prediction of number of cases
  • Landscape analysis: metrics, fragmentation, LULCC detection
  • Optimal distribution of health services
  • Location of best routes to hospitals
  • etc.

What about remote sensing?

What can we see with remote sensing to contribute to disease ecology?

viewof looksWeight = Inputs.range([-2, 2], { value: 0.7, step: 0.01, label: "looks weight" })
viewof minimum = Inputs.range([-2, 2], { value: 1, step: 0.01, label: "min fame" })
